Abstract

A directly actuated electric valve is proposed that has a piezoelectric drive unit (3) for direct actuation of a valve member (2). The piezoelectric drive unit (3) contains, extending transverse to the displacement direction of valve member (2), at least one piezo-flexural element (8, 8'), which acts on valve member (2) at one end and is mounted stationary with respect to the housing at the other, such that its electrically induced flexural motion produces the linear displacement motion of valve member (2). Such a configuration permits very short switching times with compact dimensions.
